Benjamin Green, 45, of Corinthian Lane, was also ordered Monday by U.S. District Judge Vanessa L. Bryant in Hartford to repay the remaining $582,074 owed to the IRS.

A federal jury convicted Green last November following a three-day trial on charges of making a false claim and obstructing IRS laws. He had been earning at least $80,000 annually from Metro-North, officials said.

Sean Beaty, a trial attorney with the U.S. Department of Justice's Tax Division, accused Green of filing a false 2008 federal tax return in which he claimed $920,063 in taxable income and $929,702 in deductions, which yielded a $616,434 refund paid by the IRS.

Authorities said Green spent the money paying off his mortgage and lines of credit, including one at the Grand Central Terminal Federal Credit Union. Beaty also accused Green of using the money on trips to Boston, Miami and Hawaii, for gifts to family members and for refurbishing his home and buying expensive items from Gucci, Brooks Brothers, Fortunoff, Armani and Apple.

Beaty claimed Green attempted to obtain additional refunds of $830,678, $276,201 and $150,240 by amending his 2005, 2006 and 2007 federal tax returns. Those refunds were not granted.
